Verdict
Emails that never bounce.
What it does
Verdict is an open-source cold outreach engine that verifies every mailbox before sending, a free, self-hosted Apollo.io and Hunter.io alternative. Email pattern discovery from public-web evidence, SMTP verification with catch-all and enterprise-gateway detection, bounce rate under 4%, person-level cooldowns, automated follow-up waves.

Verdict is the truth layer for your cold outreach stack. Run an SMTP verification gate over the lists Apollo, Hunter, Instantly or Clay give you, hold bounce rate under 4%, and never let a dead address ship. Open source and self-hosted. make cold mailing great again.
Verdict probes every mailbox over SMTP and refuses to send what will bounce. No contact database, no credits, no guessing — evidence, or it does not ship. And because it runs on your machine, your list is never uploaded anywhere. Not even to us. Apollo, Hunter, Instantly, Clay — they hand you a list. Nobody tells you one in ten of those mailboxes is a dead letter. Verdict is the gate that sits in front of any list you already bought, so every address proves it is alive before it ships. SPF, DKIM, DMARC and MX are what stop a stranger sending mail as you — and what decide whether your own mail is believed. Most companies have never read their own.

I made OwnTime to balance between competing priorities in my life. The idea is based on two main influences: the concept of "roles" from "The 5 Choices" (2015), and my repeated failure to effectively implement time blocking due to the necessary flexibility in my role. The app allows you to define time budgets, which are not much more than a few mutually exclusive countdown timers. The UX is essentially that of a chess clock for an arbitrary number of players with configurable time. The whole point of the app is to kick you out of the running role/priority when its time is up.
